Michael Winterbottom has admitted filming the violent scenes in his new movie was "difficult" for some of the stars.

The director's flick The Killer Inside Me has led to accusations, from some people who have seen the movie, of misogyny over violence against its female characters.

Michael said: "There were difficult days, the days of the violence, where I think Casey (Affleck) found it quite hard to find some way into being Lou Ford, something that he thought would be believable and true to how Lou Ford would be in those situations."
